  Refine `noGivenNewtypeReprEqs` to account for quantified constraints
  
  This little MR fixes #26020.  We are on the edge of completeness
  for newtype equalities (that doesn't change) but this MR makes GHC
  a bit more consistent -- and fixes the bug reported.

  wasm: mark freeJSVal as INLINE
  
  This patch marks `freeJSVal` as `INLINE` for the wasm backend. I
  noticed that the `freeJSVal` invocations are not inlined when
  inspecting STG/Cmm dumps of downstream libraries that use release
  build of the wasm backend. The performance benefit of inlining here is
  very modest, but so is the cost anyway; if you are using `freeJSVal`
  at all then you care about every potential chance to improve
  performance :)

  wasm: add zero length fast path for fromJSString
  
  This patch adds a zero length fast path for `fromJSString`; when
  marshaling a zero-length `JSString` we don't need to allocate an empty
  `ByteArray#` at all.
